You can get a pretty good idea simply by observing your inside waste plumbing. I don't think I've seen one that didn't leave the house at a straight line to the tank (no sense getting a "hang-up" before it gets to the tank). Length from the house...if you have a clean-out in the house (or maybe even a floor drain close to the exit which I guess satisfies code) a garden hose or drain snake or even a piece of stiff wire can be run through the pipe to tell you the length to the tank (protect your floors of course and maybe wear gloves). From there you should have a good idea of location. Get a sharp stick or something and start probing in that area. You have no idea how deep it is so it may take awhile.
On a slab, no known cleanouts.
